Indeed you are right, wstools does not go along with more complex types necessary for attachment. One has to do them by hand, or using a place holder. As for the mapping error, in your jaxrcp-mapping.xml do you place strings as: <param-type>java.lang.String</param-type>? And in your wsdl file, do you have them as: .... type='xsd:string'/>? Note: the prefix xsd is linked with the following namespace (xmlns:xsd='http://www.w3.org/2001/XMLSchema'>) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3985797#...
